[0031] In the following, the embodiments of the present invention will be described with reference to the accompanying drawings. The present invention will be described in detail so that those skilled in the art can easily carry out the invention. However, the present invention may be embodied in many different forms and the embodiments set forth herein may be modified in various ways. However, it is not limited to the above.

[0032] FIG. 1 is a flowchart for determining whether an abnormality has occurred in the aerosol generating device.

[0033] Referring to step 110, the control unit determines the operating state of the aerosol generating device. The operating state of the aerosol generating device is also divided into a heated state and a non-heated state.

[0034] The control unit controls the heater by determining the operating state through a first circuit unit. The control unit can monitor the current. Based on the monitoring result, the control unit When the control unit detects that a current of a predetermined value or more flows through the circuit unit, the control unit changes the operating state to heating. When a current less than a predetermined value flows in the first circuit portion, the first circuit portion is determined to be in a low-voltage state. In this case, the operating state can be determined to be a non-heating state.

[0035] The non-heating state is also divided into a charging state and a standby state. When the controller receives a current from an external charging device via the The operating state of the generating device can be determined as a charging state. If no current is received from the external charging device, the control unit senses this and controls the aerosol generator. The operating state of the device can be determined to be a standby state.

[0036] Referring to step 120, the control unit determines whether the first aerosol generating device is in operation based on the operating state of the aerosol generating device. The second circuit portion may be in communication with the first circuit portion.

[0037] For example, the control unit may, based on the operating state of the aerosol generating device, It can communicate with the first circuit unit, and in a non-heated state, it can communicate with the second circuit unit.

[0038] The control unit inputs data to the first circuit unit or the second circuit unit, or or by receiving data from the second circuit unit, the first circuit unit or the second circuit unit Communication is possible.

[0039] Based on the operating state of the aerosol generating device, when the control unit is in a heated state, the first circuit unit and In the non-heating state, the control unit communicates with the second circuit unit. Depending on the state, the main communication target is set to either the first circuit unit or the second circuit unit. In other words, it may mean communicating with a circuit unit that is set as the primary communication target.

[0040] In one embodiment, when the aerosol generating device is operated in a heated state, the control unit and communicating with the first circuit unit and receiving data on the amount of first current flowing through the first circuit unit. In another embodiment, when the aerosol generating device is operated in an unheated state, the The control unit communicates with the second circuit unit and receives data on the amount of second current flowing through the second circuit unit. It is possible.

[0041] In still another embodiment, the control unit inputs the first data to the first circuit unit in the heating state. After a predetermined time has passed, the second data is read from the first circuit unit. The control unit can detect an abnormality in the first circuit unit based on the first data and the second data. The first circuit section can also determine whether an abnormality has occurred in the control section. This is explained in more detail in FIG.

[0042] Referring to step 130, the control unit determines the operating state of the aerosol generating device based on the communication result. It is possible to determine whether an abnormality has occurred due to the state of the system.

[0043] An abnormality in the aerosol generating device is a hardware configuration abnormality in the aerosol generating device. This may mean that at least one component does not work or malfunctions.

[0044] For example, the first circuit section can heat the heater according to a pre-designed temperature profile. If the battery cannot be charged, it may be due to an abnormality in the first circuit. If the battery is not charging even though it is connected, an abnormality in the second circuit This is also why this has arisen.

[0045] The control unit determines whether an abnormality has occurred in the aerosol generating device based on the data received and each This can also be achieved by comparing the operating conditions with the critical range already specified. In one embodiment, when the control unit determines that the operating state of the aerosol generating device is a heating state, The control unit receives the first current amount data from the first circuit unit and specifies the amount of current suitable for heating the heater. By comparing the measured value with the first critical range, it is possible to determine whether an abnormality has occurred in the aerosol generating device. It can be determined.

[0046] In another embodiment, the control unit determines that the operating state of the aerosol generating device is a non-heating state. In this case, the control unit determines whether the second current amount data received from the second circuit unit is in a charging state or a standby state. By comparing the second critical range specified to suit the state of the aerosol generating device It is possible to determine whether an abnormality has occurred.

[0047] The embodiment described with reference to FIG. 1 can be summarized as follows.

[0048] When the control unit determines that a current amount equal to or greater than a predetermined value flows in the first circuit unit, In the heating state, the control unit determines the state of the device to be a heating state. The first circuit section can receive data on the amount of first current flowing through the first circuit section. The control unit then determines whether an abnormality has occurred in the first circuit unit based on the first current amount data. can be determined.

[0049] When the control unit determines that an amount of current less than a predetermined value flows in the first circuit unit, In the non-heating state, the control unit can determine the state of the device as a non-heating state. The second circuit section can receive second current amount data flowing through the second circuit section. The control unit then determines whether an abnormality has occurred in the second circuit unit based on the second current amount data. It can be determined.

[0050] FIG. 2 is a schematic conceptual diagram of an aerosol generating device.

[0051] Referring to FIG. 2, the aerosol generating device 100 includes, as a hardware configuration, a control unit 1 01, a first circuit section 102, a second circuit section 103, a battery 104, a heater 105, a temperature sensor The charging terminal 106 and the charging terminal 107 are also included. However, there are no limitations to the above-mentioned configuration. It is understood that the present invention is not limited to the above and may further include other necessary components. It will be understood by those skilled in the art. This configuration is not limited to the arrangement structure of FIG. 2, but may also be arranged in other configurations.

[0052] The charging terminal 107 receives power from an external charging device in response to being connected to the external charging device. The applied current is applied to the second circuit unit 103. This allows current to flow to the battery 104, thereby charging the battery 104.

[0053] Meanwhile, the charging device may use either a wired charging method or a wireless charging method. This can be used with a 5-pin terminal, an 8-pin terminal, or a USB ( The wireless charging method uses a magnetic field. The inductive coupling method, the capacitive coupling method using an electric field, and the high frequency radiation method are used. However, the charging device is not limited to the above-mentioned examples. It is understood by those skilled in the art that other forms of charging devices may also be included. If you are an engineer, you will understand.

[0054] The battery 104 provides the power necessary for the aerosol generating device 100 to operate. The battery 104 may be a rechargeable battery or a single-use battery. The battery 104 may also be a lithium polymer (LiPoly) battery, but there is no restriction on this. It is not limited to:

[0055] The battery 104 is electrically connected to the second circuit unit 103. For example, the current applied through the charging terminal 107 is The current flows to the battery 104 via the second circuit section 103, thereby charging the battery. Also, under the control of the second circuit section 103, the electric energy stored in the battery 104 is released. and aerosols such as the control unit 101 and the first circuit unit 102 are connected via the second circuit unit 103. It is possible to supply current to other hardware components within the rule generating device 100.

[0056] The aerosol generating device 100 also includes a temperature sensor 106. The controller 106 measures the temperature of the heater 105 and transmits the temperature data to the control unit 101. The control unit 101 then takes the received temperature data into consideration and calculates the temperature of the aerosol generating device 10. It is possible to determine whether an abnormality of 0 has occurred.

[0057] As described above, the second circuit unit 103 is electrically connected to the battery 104. The charging and discharging of the 04 can be controlled.

[0058] After the charging terminal 107 is connected to the external charging device, the second circuit unit 103 The second circuit unit 103 receives current from the charging terminal 107. In this case, the aerosol generating device can operate in a charged state, and the second circuit unit 1 03 supplies the current received from the charging terminal 107 to the battery 104, thereby The battery 104 can be charged.

[0059] When the charging terminal 107 is not connected to the external charging device, the aerosol generating device is in standby mode. The second circuit section 103 can operate in a cold or heated state, and the second circuit section 103 can operate in a cold or heated state. and receives current from the aerosol generating device 100 and controls the operation of other hardware components provided in the aerosol generating device 100. At this time, the battery 104 is discharged. As shown in the figure, the second circuit unit 103 supplies power to the control unit 101 and the first circuit unit 102. flow can be supplied.

[0060] Specifically, when the aerosol generating device 100 is in a heated state, the second circuit unit 103 The battery 104 is connected to the heater 105 so that the heater 105 can be heated according to a pre-designed temperature profile. The electric energy stored in the power supply 101 is discharged, and a current flows through the control unit 101 and the first circuit unit 102. It is possible.

[0061] When the aerosol generating device 100 is in a standby state, the second circuit unit 103 is 4 to discharge the electrical energy stored in the control unit 101 and maintain the standby state. At the same time, the current flow can be limited to the necessary amount. Therefore, it is possible to prevent current from flowing through the first circuit portion 102.

[0062] When the aerosol generating device 100 is in a charging state, the second circuit unit 103 4 is charged by receiving current through charging terminals 107. In this way, the second circuit unit 103 receives the current from the charging terminal 107 and supplies it to the battery. The amount and direction of the current can be controlled so that it flows through the terminal 104. In this way, the second circuit unit 103 is configured to charge the battery 104 in the charging state. In the heating and standby states, the current flow can be controlled. 4, it is possible to control the flow of current to each component of the aerosol generating device 100. .

[0063] The second circuit unit 103 receives power from the electrically connected charging terminal 107 via an external charging device. The control unit 101 controls the second circuit unit 103 to receive a current from an external charging device. The device detects the supply of aerosol and determines the operating state of the aerosol generating device as a charging state or a standby state. It can be determined.

[0064] According to one embodiment, the second circuit portion 103 also includes a number of switches. Receive control signals from 101 or control the on / off of multiple switches According to one embodiment, the amount of current for charging or discharging can be controlled by the The circuitry 103 includes at least one processor and a memory for storing computer code. The computer code may also include a When executed, the function of the second circuit unit 103 (for example, switching a number of switches, We will also try to cancel the event.

[0065] The first circuit section 102 receives the current output from the battery via the second circuit section 103. The first circuit section 102 controls the heater 105 from the control section 101. A signal for controlling the heater 105 is input, and a current is supplied to the heater 105. Control the temperature.

[0066] For example, the first circuit section 102 may include a plurality of switches. receives a control signal from the control unit 101 and controls the on / off of a plurality of switches. This allows the current supplied to the heater 105 to be controlled. The first circuitry 102 includes at least one processor and a computer code storage device. The computer code may also include a memory. When the first circuit unit 102 is implemented by the The first circuit unit 102 performs the following operations: (stopping the operation itself, changing data) Although it is subordinate, it can actively control its own functions in the same way as the control unit 101. As a result, the first circuit section 102 can actively control the operation of the heater 105. In the heating state, the first circuit portion 102 is electrically controlled by the heater. Appropriate control signals can be transmitted to heat the sol-forming material.

[0067] In addition, if an abnormality occurs in the control unit 101, the first circuit unit 102 will automatically stop its own operation. For example, the current flowing through the first circuit section 102 can be stopped by the first circuit section 102. The first circuit unit 102 may also be shut down by itself. Even if an abnormality occurs in the control unit 101, a safety accident can be prevented through the self-stop method. It is possible.

[0068] The first circuit section 102 has an appropriate range for controlling the heater 105 in the heating state. A current of 100 mV or less must flow through the first circuit portion 102, and a low current or an overcurrent must flow through the first circuit portion 102. If the temperature is too high, the target temperature profile of the heater 105 becomes difficult to control.

[0069] For example, if an abnormality occurs in the first circuit section 102, the first circuit section 102 The heater cannot supply the current required to heat the material. If the heater 105 is not heated, a feedback signal is generated to heat the heater 105 to the desired temperature. The voltage is applied repeatedly, causing an overcurrent to flow through the first circuit unit 102, which may result in a safety accident.

[0070] On the other hand, if almost no current flows through the first circuit portion 102, the heater 105 does not need to operate for heating. Therefore, it is difficult to heat the aerosol-generating material sufficiently. By periodic communication between the control unit 101 and the first circuit unit 102, It is necessary to receive the first current amount data to be used.

[0071] In one embodiment, the first circuit section 102 includes a monitor for monitoring the current flowing through the first circuit section 102. The current monitor also includes a current monitoring circuit that can be used to monitor the current. The ring circuit monitors the current to allow the control unit 101 to determine the operating state. It is also used for

[0072] The control unit 101 actively controls each hardware configuration to control the aerosol generation. The control unit 101 performs overall control of the device 100. The control unit 101 includes at least one processor and memory. In one embodiment, the memory is a controller unit. The library can store computer code, the computer code comprising at least When executed by one processor, at least one processor is a control unit 101 and to carry out the functions of

[0073] Referring to FIG. 2, a control unit 101 controls a first circuit unit 102 and a second circuit unit 103. As described above, the control unit 101 controls the first circuit unit 102 to control the heating state. The temperature of the heater 105 is controlled to be a temperature suitable for heating the aerosol generating material. It is possible.

[0074] In addition, in the non-heating state, the control unit 101 controls the second circuit unit 103 to Depending on the battery or charging state, current may be discharged from the battery 104 or may be applied to the battery 104. Allow the current to charge.

[0075] In addition, the control unit 101 can determine the operating state of the aerosol generating device 100. .

[0076] The control unit 101 monitors the current flowing through the first circuit unit 102 and determines whether the current value is equal to a predetermined value. If it is equal to or greater than the predetermined value, it is determined to be in a heated state, and if it is less than the predetermined value, it is determined to be in a non-heated state. The non-heating state may include a charging state or a standby state.

[0077] The control unit 101 determines whether the second circuit unit 103 is supplied with current from an external charging device. Based on this, the operating state of the aerosol generating device 100 is set to either a charging state or a standby state. You can decide on one of them.

[0078] For example, the second circuit unit 103 is connected to an external power source via a charging terminal 107 in order to receive a current. The current supplied from the charging terminal 107 is transferred to the second circuit unit 103. The control unit 101 senses the current or electrical signal flowing through the second circuit unit 103. On the other hand, the control unit 101 can detect the charging terminal and determine the operating state as the charging state. When the current flowing through the second circuit unit 103 cannot be detected via 107, The control unit 101 can determine that the operating state of the aerosol generating device is a standby state.

[0079] The control unit 101 also communicates with the first circuit unit 102 and the second circuit unit 103. The current amount data and the second current amount data are received, and the first circuit unit 102 and the second circuit unit 103 It is possible to periodically and repeatedly determine whether an abnormality occurs in the aerosol generating device 100 due to the Cut.

[0080] Specifically, the control unit 101 monitors the current flowing through the first circuit unit and determines whether the aerosol The operating state of the generating device 100 is determined, and first current amount data is obtained from the first circuit unit or the second circuit unit. The first or second current amount data can be received to periodically determine whether an abnormality has occurred.

[0081] For example, when a current suddenly flows through the first circuit section where no current has been flowing, the control section 101 In this case, the operating state of the aerosol generating device can be determined to be the heating state, and the first current amount data It receives data and can determine whether an abnormality has occurred.

[0082] The control unit 101 determines whether the first current amount data received from the first circuit unit 102 is the first temporary current amount data. If the second current amount data received from the second circuit unit 103 exceeds the specified range, It is possible to confirm that the second critical range has been exceeded and determine whether an abnormality has occurred.

[0083] On the other hand, the control unit 101 detects the temperature of the heater 105 through a temperature sensor 106 located adjacent to the heater 105. The temperature data of the heater 105 can be received. When determining whether the device 100 is malfunctioning, additional considerations include the aerosol generation Which hardware configuration in the aerosol generation device 100 causes an abnormality in the aerosol generation device 100? This allows for a more precise understanding of how much

[0084] For example, if the first current amount data acquired by the control unit 101 is within a first critical range (for example, normal The temperature data is within the normal range, and is compared with the pre-designed temperature profile. If the temperature is not within the range (for example, the normal range), the control unit 101 determines that the cause of the abnormality is the heater 105 Alternatively, it can be determined that the sensor 106 is in the position where the user is standing. can provide a warning to the operator of a heater 105 or sensor 106 failure.

[0085] As another example, in the case of induction heating, the first current amount data of the first circuit unit 102 is within the normal range. If the voltage is lower than the normal range, it may be due to an abnormality such as a broken coil. You can let the user know that something is wrong.

[0130] In addition, a plurality of susceptors 602 can be arranged in the aerosol generating device 100. The plurality of susceptors 602 are also arranged to be inserted into the cigarette 200. Some of the susceptors 602 are also disposed outside the gullet 200. The remaining part is arranged to be inserted inside the cigarette 200, and the remaining part is arranged outside the cigarette 200. The shape of the susceptor 602 is not limited to the shape shown in FIG. They are also manufactured in a variety of shapes.

[0131] An example of a cigarette 200 will now be described with reference to FIG.

[0132] FIG. 7 is a diagram illustrating an example of a cigarette.

[0133] Referring to FIG. 7, the cigarette 200 comprises a tobacco rod 210 and a filter rod 22 The first portion 210 described with reference to Figures 3 to 5 includes the tobacco rod 210. The second portion 220 includes a filter rod 220 .

[0134] Although FIG. 7 illustrates the filter rod 220 as a single segment, it is not limited thereto. In other words, the filter rod 220 is made up of multiple segments. For example, the filter rod 220 may have a first segment that cools the aerosol. and a second segment that filters out certain components contained in the aerosol. If necessary, the filter rod 220 may also include a small number of components that perform other functions. It also includes at least one further segment.

[0135] The cigarette 200 is also wrapped in at least one wrapper 240. 40 has at least one hole through which external air flows in or internal gas flows out. As an example, the cigarette 200 may also be wrapped by a single wrapper 240. In another example, the cigarette 200 may be wrapped in two or more wrappers 240 in a stacked manner. For example, the tobacco rod 210 is wrapped by a first wrapper and then wrapped by a second wrapper. The filter rods 220 can then be wrapped in individual wrappers. The baco rod 210 and the filter rod 220 are connected, and the cigarette is The entire 200 may be further wrapped. If the tobacco rod 210 or filter rod 220 If each consists of multiple segments, each segment must be individually wrapped. The segments wrapped by the individual wrappers are then combined. The entire wrapped cigarette 200 is then further wrapped in another wrapper.

[0136] The tobacco rod 210 includes an aerosol-forming material. For example, the aerosol-forming material may be , glycerin, propylene glycol, ethylene glycol, dipropylene glycol, Diethylene glycol, triethylene glycol, tetraethylene glycol and oleic acid These may also contain, but are not limited to, at least one of the following alcohols: The tobacco rod 210 also contains no flavoring agents, humectants, and / or organic acids. The tobacco rod 210 may also contain other additives such as menthol. Flavoring liquid such as humectant or humectant may also be added by spraying it onto the tobacco rod 210. will be done.

[0137] The tobacco rod 210 may be made in a variety of ways. For example, the tobacco rod 210 may be made from a sheet It can also be made from sheets and strands. Bacolod 210 can also be made from shredded tobacco, where the tobacco sheet is cut into small pieces. The tobacco rod 210 is also surrounded by a thermally conductive material. The material may be, but is not limited to, a metal foil such as aluminum foil. As an example, a heat conducting material surrounding the tobacco rod 210 may be used to conduct heat to the tobacco rod 210. This allows the heat to be evenly distributed and improves the thermal conductivity of the tobacco rod. This can improve the tobacco taste. The surrounding thermally conductive material acts as a susceptor that is heated by an induction heater. At this time, although not shown in the drawings, the tobacco rod 210 is removed from the outside. In addition to the surrounding thermally conductive material, it may also further include an additional susceptor.

[0138] The filter rod 220 is also a cellulose acetate filter. There is no limitation on the shape of the filter rod 220. For example, the filter rod 220 may be a cylindrical rod. The filter rod 220 is a tube-shaped rod having a hollow inside. If the filter rod 220 is made up of multiple segments, In this case, at least one of the plurality of segments is also fabricated with a different shape.

[0139] The filter rod 220 may also be made to produce a flavor. The scented liquid is sprayed onto the filter rod 220, and the applied fibers are then sprayed onto the filter rod 220. It is also inserted internally.

[0140] The filter rod 220 also includes at least one capsule 230. Here, the capsule 230 can also perform the function of generating flavor, and For example, the capsule 230 may contain a fragrance. The capsule 230 has a spherical or cylindrical shape. It can have, but is not limited to, the following:

[0141] If the filter rod 220 includes a segment that cools the aerosol, the cooling The cooling segment may also be made of a polymeric or biodegradable polymeric material. For example: The cooling segment may also be made solely of pure polylactic acid, but is not limited to it. Alternatively, the cooling segment may be protected by a multi-hole cellulose acetate filter. However, the cooling segment is not limited to the above example. Without limitation, any device capable of performing the function of cooling the aerosol may be used. It's possible.

[0142] On the other hand, although not shown in FIG. 7, the cigarette 200 according to one embodiment has a front end flap. The front end filter is a filter in the tobacco rod 210. The front end filter is located on the side opposite the tobacco rod 210. The tobacco rod 210 can be prevented from escaping to the outside, and the tobacco rod 210 can be prevented from being liquefied during smoking. The aerosol is prevented from flowing into the aerosol generating device 100 (FIGS. 3 to 6). It can be stopped.

[0143] FIG. 8 shows a diagram illustrating a method for detecting an abnormality in a device based on the first current amount data or the second current amount data according to an embodiment. 10 is a flowchart for determining whether a normal state is normal or not.

[0144] Referring to step 810, a control unit (e.g., control unit 101) controls an aerosol generating device (e.g., For example, the current operating state of the aerosol generating device 100 is either a heated state or a non-heated state. It can be determined whether the state is

[0145] The control unit detects whether a current amount equal to or greater than a predetermined value flows in the first circuit unit (for example, the first circuit unit 102). If it is determined that the operating state of the aerosol generating device is a heated state, the operating state of the aerosol generating device can be determined to be a heated state. The control unit also detects that a current less than a predetermined value flows through the first circuit unit. The state can be determined to be a non-heated state.

[0146] In one embodiment, the aerosol generating device includes a system that detects when a cigarette is inserted. The cigarette insertion sensor may further include a cigarette insertion sensor. After detecting that the insertion of the sensor is detected, the sensor transmits a detection signal to the control unit. In response to the signal, the second circuit unit (for example, the second circuit unit 103) is controlled to charge the battery (for example, For example, the current of the battery 104 is applied to the first circuit section. If a current exceeding a predetermined value flows, the control unit detects it and then turns off the aerosol generating device. The operating state of the device can be determined as a heating state.

[0147] In another embodiment, the aerosol generating device includes a user interface for receiving user input. The control unit receives an input signal from the user interface. The control unit controls the second circuit unit in response to receiving the input signal. The battery current is controlled so that it is applied to the first circuit section. When the current flows, the control unit detects it and controls the aerosol generating device. The operating state can be determined as a heating state.

[0148] If the operating state of the aerosol generating device is determined to be the heating state, proceed to step 820. If the operating state of the aerosol generating device is determined to be the unheated state, proceed to step 840.

[0149] Referring to step 820, if the operating state is the heating state, the control unit controls the first circuit unit to The first current amount data flowing through the power supply can be received.

[0150] When the operating state of the aerosol generating device is determined to be the heating state, the control unit sets the main communication target as In the heated state, the aerosol generated by the first circuit section can be determined. In order to determine whether an abnormality has occurred in the current generating device, the control unit can be received periodically.

[0151] Referring to step 830, if the operating state is the heating state, the control unit detects a temperature sensor (e.g., For example, temperature data can be additionally received from a temperature sensor 106. This is an optional step, and temperature data is added when determining whether an abnormality has occurred in the aerosol generating device. can be considered as such.

[0152] Referring to step 840, if the operating state is the non-heating state, the control unit controls the second circuit unit The second current amount data flowing through the aerosol generating device is acquired. If it is determined that the second circuit unit is the primary communication target, the control unit can determine that the second circuit unit is the primary communication target. In a thermal state, the second circuit section determines whether an abnormality has occurred in the aerosol generating device. The control unit can periodically receive the second current amount data of the second circuit unit.

[0153] Referring to step 850, when the operating state is the heating state, based on the first current amount data, It is possible to determine whether an abnormality has occurred in the aerosol generating device.

[0154] Specifically, the first current data and the first critical range, which is the range of current expected in the heated state, If the first current amount data is outside the first critical range, an abnormality is detected in the aerosol generating device. It can be determined that a malfunction has occurred.

[0155] In one embodiment, the control unit determines whether the aerosol is present or not based on the first current amount data and the temperature data. For example, the control unit can determine whether an abnormality has occurred in the generating device. By receiving additional heater temperature data from the first circuit, in the heating state, It is possible to determine which of the components, the heater or the part, is experiencing an abnormality. can.

[0156] If the temperature data is not taken into account, it is difficult to know whether the heater is malfunctioning. However, by adding the temperature data, By taking this into consideration, it is possible to determine more precisely whether abnormalities occur during heating. can.

[0157] Referring to step 850, if the operating state is a non-heating state, based on the second current amount data, It is possible to determine whether an abnormality has occurred in the aerosol generating device. The flow rate data is compared with the second critical range, which is the range of current flow expected in an unheated state, and the second critical range is If the current data falls outside the second critical range, it is determined that an abnormality has occurred in the aerosol generator. It is possible.

[0158] The control unit determines whether the current state of the aerosol generating device is a charging state or a standby state. In either case, the second current magnitude data can be monitored periodically. The second critical range of the second current amount data is different between the charging state and the standby state. It is also specified to be.

[0159] For example, in the charging state, current is supplied via the charging terminal, so the charging time is longer than in the standby state. In the power-on state, more current can be expected to flow through the second circuit portion. Therefore, the second critical range is greater in the charging state than in the standby state. and may be specified even higher.

[0160] In this way, the aerosol generating device can be used not only in a charging state but also in a standby state. Periodically, second current amount data is received and a second critical range is set to be suitable for the standby state. By comparing, safety can be prevented from potential dangerous accidents in all operating states. This can be done.

[0161] In step 850, the first critical range or the second critical range is simply set to a first current amount, respectively. In addition to comparing the data or the second current amount data, as described in Figure 2, Temperature data can additionally be taken into account.

[0162] For example, if the temperature data is within the normal range but an overcurrent flows through the first circuit, The first current amount data exceeds the first critical range, causing the first circuit unit to malfunction. It can mean:

[0163] In another example, the first current amount data is within the first critical range, but the temperature data is below the heating temperature. If the heater cannot reach the specified range, it means that the first circuit is not applying enough current to the heater. This may indicate a malfunction of the heater.

[0164] As another example, in the case of induction heating, the first circuit unit operates normally and the first current amount data is If the temperature of the susceptor does not rise even though it is within the first critical range, the induction It could also mean that the coil has an open circuit.

[0165] As another example, the battery may not be charged even though the second circuit section is in a charging state. If the current consumption increases without any change, it may indicate a malfunction of the second circuit unit.

[0166] As another example, even though the second circuit unit is in standby mode, the battery may be used. If a current exceeding this limit flows, an excessive current greater than necessary may flow in the second circuit section during standby. It is possible that the second current amount data exceeds the second critical range, and the second circuit section This may mean a malfunction.

[0167] Referring to step 860, the control unit determines whether or not an abnormality has occurred in the aerosol generating device through the above series of steps. If it is determined that the device is dead, the aerosol generator is reset, the first circuit section stops operating, and the battery current is cut off. Various actions can be ordered, such as shutting down the device or issuing a warning to the user.

[0168] Specifically, when an overcurrent flows in the first circuit unit in the heating state, the control unit In order to stop the operation of the circuit section, the second circuit section or the Alternatively, the electrical connection to the battery can be cut off.

[0169] Or, if an abnormality occurs in the control unit itself, in order to reset the aerosol generating device, This includes initializing the state of all hardware components inside the aerosol generating device. There are also.

[0170] Alternatively, when an overcurrent flows through the second circuit unit in a non-heated state, the control unit The electrical connection with the battery or charging terminal is cut off so that no current can be applied to the part. The flow can be blocked from flowing to the second circuit portion.

[0171] The aerosol generating device also provides a warning notice to the user. The device is equipped with a user interface, LED (Light Emitting Diode) or vibration motor. The device further includes a warning indicator, such as a flashing LED, or a warning message, which may be displayed via a user interface. Alternatively, it may include vibrating to notify the user of the warning. In addition to the notification methods exemplified above, other methods may be used. Furthermore, it is understood by those skilled in the art that the present invention relates to the present invention. If so, you will be able to understand.

[0172] Specifically, in the heating state, the first current amount data falls within the specified first critical range. If the heater overheats despite the fact that the first circuit unit is The second circuit section is connected to the power supply so as to cut off the current flowing through the first circuit section and prevent the power supply from overheating. It can control the temperature and can provide the user with a heater overheat warning.

[0173] Furthermore, even though there is no temperature rise in the heater, the first current amount data of the first circuit section is If the critical range is exceeded, the control unit can stop the operation of the first circuit unit. In the case of heat, no induced current occurs, but if an overcurrent is applied to the induction coil, It is possible to notify the user of any coil breakage or abnormality.

[0174] Further, the aerosol generating device, in a charged state, If the battery is not charging properly despite being within the critical range, an abnormality has occurred in the battery. and can provide a warning that a battery failure has occurred.

[0175] Alternatively, the aerosol generating device may be configured to: 2. When the device is not in the critical range or is in standby mode, the second current data indicates a charging state. If the second critical range is not met, it is determined that an abnormality has occurred in the second circuit. In addition, a warning notice can be given to notify the occurrence of a failure in the second circuit section.

[0176] In addition, in the charging state, the second current amount data flowing through the second circuit unit is within the second critical range. If the value is much lower than the range, it may not be charging properly and may cause a malfunction. On the other hand, if the second current amount data has a very high value, it is possible that the battery is in trouble due to overcharging. To prevent this, the aerosol generating device has a second circuit section that is connected to the battery. It is possible to cut off the current flowing through the

[0177] In addition, the aerosol generating device is not charged, and the measured current amount is higher by the second current amount data. In this case, the user is notified of the battery replacement, or the second time is The current flowing through the path can be interrupted.

[0178] In addition, in the standby state, the second current amount data flowing through the second circuit unit is higher than the second critical range. If the battery is not fully charged, the control unit, the first circuit unit, or the heater may be overloaded with current. This will also flow into other hardware components of the aerosol generating device, including the The generator may interrupt the current flowing from the second circuit section to other components, or may notify the user 2. A fault notification signal can be given for the circuit section.

[0179] FIG. 9 is a flowchart for determining whether an apparatus malfunctions based on a communication result according to an embodiment. It is.

[0180] Referring to step 900, this means that the aerosol generating device is operating normally. If no abnormalities are found in the general current monitoring or data communication monitoring This also applies.

[0181] Referring to step 910, the control unit determines whether the current operating state is a heating state or a non-heating state. It can be determined whether the device is in a heated state or not. The thermal state is determined by the control unit as described above, see step 920. In other words, when the operating state is the heating state, the control unit inputs the first data to the first circuit unit. If there is no abnormality in the control unit, the first data is input to the first circuit unit. When this normally occurs, the first data is not input to the first circuit unit.

[0182] Referring to step 930, after the control unit inputs the first data to the first circuit unit, a predetermined time is elapsed. After the first circuit has been operated normally, the second data can be read from the first circuit. If the first data is received from the control unit, after a certain time has elapsed, the first data is transmitted. The data can be changed to the second data. For details, refer to Figure 10. This will be discussed later.

[0183] Referring to step 940, the control unit determines whether the first data and the second data are the same. If they are the same, go to step 950; if they are not the same, go to step 960. If there is no such data, the first circuit unit has changed the first data to the second data. It is determined that the circuit unit operates normally, and the process returns to step 900. If the second data is not the same, both the control unit and the first circuit unit operate normally. is also understood.

[0184] Referring to step 950, the first data and the second data being the same means that the first data is the same as the second data. This can be understood as being because the circuit unit cannot change the first data to the second data. As a result, the control unit determines that an abnormality has occurred in the first circuit unit and stops the operation of the first circuit unit. It is possible.

[0185] Referring to step 960, in step 920, the control unit inputs first data to the first circuit unit. The reason why the control unit was unable to output the data is thought to be due to a malfunction of the control unit. It is also determined that this is due to

[0186] If an abnormality occurs in the control unit, the first circuit unit receives a command from the control unit and stops operation. Therefore, the first circuit section will stop operating by itself, and the heater will overheat or the first circuit section will overcurrent. This can prevent safety accidents such as the following.

[0187] Steps 970 through 990 are the non-heating portion of the flowchart of FIG. , steps 850 and 860).

[0188] FIG. 10 is a conceptual diagram illustrating a communication method between the control unit and the first circuit unit according to one embodiment. Figure.

[0189] The control unit 101 periodically inputs (writes) first data 1020 to the first circuit unit 102. (1010) Both the control unit 101 and the first circuit unit 102 actively perform the control function. However, the control unit 101 and the first circuit unit 102 are configured as a master device and a slave device. (slave) It is also related to the device.

[0190] The master device is the main actor in the execution of one task and controls other slave devices. On the other hand, the slave device can control the master device. It is a device that can receive instructions from the master device and perform operations. .

[0191] That is, the control unit 101 can control the first circuit unit 102, but the first circuit unit 102 cannot control the control unit 101. For example, the control unit 101 Input data to the first circuit section 102 (1010) or read data from the first circuit section 102. The first circuit unit 102 can read (1050) the data, but the first circuit unit 102 inputs the data to the control unit 101. Otherwise, the data cannot be read from the control unit 101.

[0192] The first data 1020 periodically checks whether communication with the first circuit unit 102 is properly performed. It is also data used to confirm whether the data transmitted from the control unit 101 is correct. The first circuit unit 102 receives the first data 1020 and converts the first data 1020 into first data 1. The data can be changed (1030) with second data 1040 different from 020.

[0193] Such a data change (1030) process is performed by the control unit 101, which reads it later ( 1050), in the process of determining whether the first data is the same as the first data 1020 There are also.

[0194] The method of changing data (1030) by the first circuit unit 102 is called a toggle method. For example, the input data is simply one bit different from other data via a toggle method. The control unit 101 checks whether the changed data is the same as the input data. By continuously comparing whether or not the communication is correct between each circuit, It consumes only a small amount of power and can be easily checked whether or not the device is turned on.

[0195] That is, if the control unit 101 is operating normally without any abnormality, the control unit 101 periodically inputting (1010) first data 1020 to the first circuit unit 102; When an abnormality occurs in the control unit 101, the first circuit unit 102 outputs the first data 1020. Since the signal is not input, the abnormality of the control unit 101 is indirectly detected via the first circuit unit 102. The condition can be confirmed.

[0196] On the other hand, if the first circuit section 102 is operating normally without any abnormality, 102 periodically updates the first data 1020 with second data 1040 that is different from the data before the first data 1020 was changed. (In FIG. 10, the second data is S2.) However, if the data modification fails, the second data will be substantially the same as the first data. (This could mean that the data is the same.)

[0197] Whether the first circuit unit 102 has correctly changed the data (1030) or not depends on the following: The control unit 101 reads data from the first circuit unit 102 (1050), and the first data 102 0 and the second data 1040 to check whether they are the same. This can be indirectly confirmed by

[0198] For example, if the first data 1020 and the second data 1040 are different, the first circuit unit 10 If the first circuit section 102 is operating correctly and the two data are different, Since the data change (1030) has failed, the first circuit unit 102 is not operating normally. It appears that this is not the case.

[0199] In this way, through periodic data communication between the control unit 101 and the first circuit unit 102, the control unit The first circuit unit 101 and the first circuit unit 102 can check whether an abnormality has occurred in each other.

[0200] That is, if an abnormality occurs in the control unit 101, the first circuit unit 102 stops its own operation. When an abnormality occurs in the first circuit section 102, the control section 101 102 is stopped, and abnormal overheating or overcurrent of the heater 105 is prevented in advance. This can be done.

It can also be embodied in the form of a recording medium containing instructions that can be executed by a computer. A computer-readable medium is any available medium that can be accessed by a computer. This includes both volatile and non-volatile media, and separable and non-separable media.
